This SBIR Phase II project, called the Athena Channelizer Technology 1, or ACT1, involves the realization of a new channelizer technology that will meet the needs of Department of Defense Transformational Communications program. Transformational communications is part of the military’s overhaul of its currently diffused communications assets into an integrated system that expands military communications capabilities by an order of magnitude (10x). A critical enabling technology is a new class of channelizer capable of assembling information channels by adaptively combining subbands found within a broadband spectrum, while also capable of efficiently operating in hostile environments using radiation tolerant components. The Athena ACT1 solution is the fusion of multiple Athena authored and demonstrated innovations in the area of multi-band channelizer design, signal processing, fault tolerance, and implementation. In Phase I, the proposed ACT1 solution was developed and analyzed. In Phase II, Athena will design and implement an ACT1 channelizer that will provide the Transformational Communications Office with an infrastructure technology capable of ensuring the reliable delivery of information under a variety of satellite-borne conditions and circumstances.
